A Binomial Distribution Model for the Traveling Salesman Problem Based on Frequency Quadrilaterals
Journal of Graph Algorithms and Applications, 2016 We study the symmetric traveling salesman problem via frequency graphs. One computes the frequency of edges by computing how many times an edge occurs in an optimal path involving four vertices. The edges that are in the Optimal Hamiltonian Cycle ($OHC$)

On a conjecture referring to orthic quadrilaterals
, 2016 In this article we will give a positive answer to a recent conjecture on orthic quadrilaterals: If a convex quadrilateral Q is cyclic and orthodiagonal, among all orthic quadrilaterals associated to Q the one of maximum area is Qpo, the principal orthic ...

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

The Napoleon’s Theorem: Synthesis and Related Investigations
Science & Philosophy, 2017 We recall a synthetic-geometric demonstration of Napoleon Theorem, which makes use of the Fermat point. Some insights on the topic related to convex Quadrilaterals will be made.

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond
Advanced Materials, EarlyView.Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Transitive sets and cyclic quadrilaterals
, 2020 Motivated by some questions in Euclidean Ramsey theory, our aim in this note is to show that there exists a cyclic quadrilateral that does not embed into any transitive set (in any dimension).
